    Why Do We Need Clamp Meter?

    Clamp meter, also known as a current clamp or current clamp, is a key tool in electronic test instruments. Clamp ammeters play a vital role in current measurement and circuit troubleshooting. ATO store will give you an overview of why we need clamp ammeters in many ways.

    What are the Types of Clamp Meter?

    The clamp meter is a portable instrument that can directly measure the AC and DC of a circuit without disconnecting the circuit. Clamp meter is easy to use and widely used in electrical maintenance. For example, a clamp ammeter can be used to measure the operating current of a running AC motor, thereby easily understanding its working conditions when there is a load. will introduce the main classifications of clamp ammeters to help you better understand the different types and applications of clamp meters.

    What is a Clamp Meter?

    The clamp meter is a combination of a current transformer and an ammeter. Usually, when measuring current with an ordinary ammeter, it is necessary to cut off the circuit to stop before the ammeter can be accessed for measurement, which is very troublesome, and sometimes the normal operation of the motor does not allow this to be done. At this time, the use of a clamp ammeter is much more convenient, you can not cut off the circuit to measure the current.

    Clamp Meter Price List

    A clamp meter, also known as a clip-on ammeter, current clamp, is an electronic test instrument used to measure current non-contact. A clamp meter is an essential tool for electricians and electronic repairers to measure current and ensure proper operation and safety of electrical circuits. ATO online shop will provide you with a range of prices for different types of clamp meters.

    How to Measure Current with a Clamp Meter?

    When the measurement is complete, the clamp meter's changeover switch should be placed at the maximum range. Generally speaking, the clamp meter has a digital display and a pointer display, when measuring approximately the approximate range of the measured current, pay attention to the choice of the clamp meter range, and try to choose the right content to reduce the error. In addition, try to clamp the wire in the middle of the jaws of the clamp meter, if the measured current is too small, you can wind the wire into more than one, and then the measured value divided by the number of roots, but also note that you can not measure the bare wire, to avoid the risk of electric shock. If it is a clamp meter that can measure voltage and other functions, the pencil should be removed when the current is measured. Further, in a three-phase load, the clamp's jaws measure the current of the line, and the clamp of two measures the current of the third.

    Clamp Meter VS. Multimeter

    Clamp meters are divided into mechanical pointer clamp meters and digital clamp meters. Its biggest advantage is that it can measure the current in the line without disconnecting the line to be measured. The current multi-function clamp meter also carries test leads and other voltage resistance gears, and can also be used as a multimeter, and the clamp current meter is also divided into pointer type and digital type, which are roughly the same as the multimeter classification, but the clamp meter head has a transformer, so it is more troublesome to carry.

    How Does a Clamp Meter Work?

    As one of the necessary test tools in daily maintenance work, the clamp meter is mainly used to test related parameters such as voltage, current, frequency, etc. It is required to have high test resolution, test accuracy and more test functions. Clamp meter is an instrument that integrates current and ammeter. It is an important branch of digital. Its working principle is the same as that for measuring current.

    How to Use a Clamp Meter?

    The digital clamp meter is a meter used to measure the current of the running electrical circuit. With this instrument, the current can be measured under uninterrupted power conditions. It can be used to measure AC and DC voltage, AC current, resistance, capacitance, diode forward voltage drop, circuit continuity, frequency and duty cycle. The greatest convenience of measuring AC current is that only one wire to be measured is placed in the intersection. Moreover, the measured AC current frequency range can be as wide as 1 kHz. The display of ATO clamp meter is equipped with background light, which is convenient for working under the condition of low light.
